74.1.1. Single - Ended Vs. Differential Signaling and Basic Model of a Differential Amplifier (Contd.)

Try these first

1. 1.

   What is the primary function of a differential amplifier?

   Hint

   Think about what we discussed regarding common mode signals.

2. 2.

   Define single-ended signaling.

   Hint

   Recall the disadvantages we discussed.

3. 3.

   What is the main purpose of a differential amplifier?

   • Amplify common signals
   • Suppress noise
   • Amplify differential signals

   Hint

   Focus on the word 'differential'.

4. 4.

   True or False: Single-ended signaling is more effective than differential signaling for rejecting noise.

   • True
   • False

   Hint

   Think about the disadvantages we discussed.

5. 5.

   In a given electronic system, discuss how ground potential differences between two devices can impact signal integrity. Propose a design that could minimize this issue.

   Hint

   Consider how differential amplification cancels noise.

6. 6.

   Evaluate the performance of an operational amplifier that shows a high common mode gain in relation to its output accuracy. What changes can you suggest to improve its performance?

   Hint

   Review the specifications necessary for effective op-amp functionality.
